While creating a General section, how do we know what is the meaning of D, B, TD and TB values for each section type selected by the GST parameter in the EN 1993-1-1:2005?

 

 
Eurocode 3 (EN 1993-1-1:2005) is the only design code in the STAAD.Pro as of now, which can design General section not only as an I section, but also as some other standard section. The table below summarizes the meaning of D, B, TD and TB values in the General section dialog for each standard section, when it is designed by using EN 1993-1-1:2005 and assigned with some specific GST parameter's value.

Section Shape	GST value	Parameters required	D	B	TD	TB
I	0	D, TD, B, TB	Depth of the section	Width of the section	Thickness of web	Thickness of single flange
Single Channel	1	D, TD, B, TB	Depth of the section	Width of the section	Thickness of web	Thickness of single flange
RHS	2	D, B, TD	Depth of the section	Width of the section	Thickness of wall	Not required
CHS	3	D, TD	External radius of pipe	Not required	Thickness of wall	Not required
Angle	4	D,B,TB	Depth of angle	Width of angle	Not required	Thickness of leg
Tee	5	D, TD, B, TB	Depth of the section	Depth of the section	Thickness of web	Thickness of flange
